+Description: IPv6 & IPv6 registration support
+ .
+ iptables (1.6.0-3) unstable; urgency=medium
+ .
+   * several changes in this release. To put it short: split packages into
+     libiptc, libip4tc, lipip6tc and libxtables-dev, so we no longer require
+     the old iptables-dev binary package.
+     .
+     Also, give to all binary packages Multi-Arch support.
+     .
+     Another important thing: move libs from /lib to /usr/lib
+     .
+     Now follows almost all the commits:
+     .
